- We developed an electroabsorption modulator module for analog 60-GHz radio-over-fiber (RoF) applications. The temperature-dependent characteristics of an electroabsorption modulator were demonstrated and analyzed from 15 ℃ to 45 ℃. The insertion loss increased from 13.1 dB to 17.2 dB and the extinction ratio from 0 V to -5 V also increased from 14.5 dB to 26.2 dB with temperature at 0-dBm input power. The optimum operation voltages with the highest modulation efficiencies at different temperatures were investigated using a 60-GHz RoF link. The gain of the RoF link decreased by as much as 7 dB from 25 ℃ to 45 ℃ at a bias voltage -1.5 V; the gain of the RoF link had a maximum value at 25 ℃. For the RoF link, a steady gain could be obtained by adjusting the bias voltage to an optimum value for the given temperature.
